IPC: B61L3/04
Abstract: 920,553. Electric selective signalling systems. GENERAL RAILWAY SIGNAL CO. April 21, 1961 [April 21, 1960], No. 14503/61. Class 40 (1). [Also in Group XXX] A central traffic control system for the control of unmanned trains operating over a plurality of rail tracks which are divided into sections by inductive markers, comprises trans-receive equipment on each train for co-operation with the markers, which on reception of a marker signal, originates a radio signal to a central office modulated with train identification and location tones, receive equipment at the central office for the reception and storage of the received signal, manual train eontrol setting means at the central office, means for originating a radio signal from the central office modulated with the train identification and location tones and with one or more operational tones determined by the setting of the manual control means and receive means on the train for reception of the central office signal and for controlling the train in accordance with the operational tone or tones. Each inductive marker, e.g. marker 18.2, includes two check in-out coils each tuned to a specific frequency, in this case frequencies B and D, which co-operate with train-carried trans-receive equipment comprising a sweep frequency oscillator and a receiver to energize, via amplifiers fB and fD, tuned to frequencies B and D, relays B and D and their repeater relays BP and DP. Pick-up of relays BP and DP energizes a location relay 18.2 LT which selects a location tone for application with a train identity tone, e.g. tone 104, selected by the position of switch TIS, to a modulator unit associated with a check in-out transmitter operating at frequency f1. The pick-up of relay 18.2 LT also energizes the transmitter which transmits the train identity and location information to a central control office. The central office receiver, Figs. 5A and 5B, includes a number of output circuits FLM each tuned to a particular location tone and a number of circuits tuned to receive the identity tones. In this case circuits FLM 182 and Train 2 East will be energized, resulting in the pick-up of relay 18.2 CIR 104, indicating at the central office that train 104 has passed location 18.2. The reception of the check in-out signal at the office initiates a transmission to the train of a signal modulated by the train location and identity tones (for address purposes) plus one or more train control tones (see Group XXX). Reference has been directed by the Comptroller to Specifccation 880,634.

Title: Oscilloscope controlled digital storage adapter
Inventor: COATES TIMOTHY PAUL VANN
IPC: G01R13/34
Filed: 1992-04-21
Abstract: An oscilloscope controlled digital storage adapter has an input gain and attenuation stage 2, an analogue to digital conversion stage 3, a digital memory 9, a digital to analogue conversion stage 4, an output gain and attenuation stage 5, and timing and control circuitry 10. The input gain and attenuation stage 2 performs scaling prior to conversion into digital form by the analogue to digital converter 3. The contents of the digital memory 9 are then read and converted by the digital to analogue converter 4. The resultant signal is fed to the output gain and attenuation stage 5 which reconstructs the original signal in terms of amplitude. The timing and control circuitry serves to prevent the contents of the digital memory 9 being displayed more than once on the oscilloscopes, screen, making use of the oscilloscopes main gate output 11 and Z modulation input 12. Full control of the oscilloscope timebase and amplitude settings are therefore allowed. <IMAGE>

Title: Television liquid crystal displaying apparatus for different line scanning standards
Inventor: HORIBE SHIGENOBU
IPC: G09G3/36
Filed: 1992-09-15
Abstract: A liquid crystal displaying panel is formed of a number of pixels in the horizontal and vertical directions based on a television system having 625 horizontal scanning lines e.g. PAL system. A polarity reversing circuit 5 reverses the polarity of an input video signal at a predetermined period and a signal feeding circuit 3 samples the video signal. The signal feeding circuit feeds the output to the respective data lines of the liquid crystal panel. For displaying a 525 scanning line signal e.g. an NTSC system signal, switches SW1-SW9 and SW101-SW140 are provided so that video signal samples are also fed to the data lines corresponding to the otherwise blank part 23 of the video displaying region. Thus by alternately driving the liquid crystal of all the pixels, a video of the same picture quality can be displayed in the PAL system and NTSC system without deteriorating the liquid crystal. When displaying a 525 line signal the region 23 may be masked so that the video displayed therein is not viewed. In further embodiments line alternating polarity signals from a separate source are fed to the display matrix pixels in region 23 when a 525 line signal is displayed. <IMAGE>

Title: Image generator
Inventor: BAKER STEPHEN JOHN
IPC: G06T15/50
Filed: 1992-11-19
Abstract: A method and apparatus for simulating the illumination effects of a vehicle mounted light source in an image displayed on a screen. The image is intended to represent the appearance of a model defined in a database in world space coordinates from an eyepoint position in world space, the model being defined in terms of a plurality of features each having predetermined attributes. The vehicle mounted light source is defined in terms of an origin and a direction in eyepoint space. For each feature potentially contributing to the image, the angular position of a point on that feature relative to the light source is calculated as the angle between the light source direction and a line drawn to that point from the light source. An illumination intensity for that point is determined by reference to the calculated angle, and the illumination intensity is reduced as a function of the distance from the eyepoint to the said point to provide a resultant intensity. The attributes of the feature at the said point are modulated as a function of the resultant intensity.

Patent GB-2283890-A (GB)
Title: Sampling signal analyzer
Inventor: MARZALEK MICHAEL S
IPC: G01R13/34
Filed: 1992-01-24
Abstract: The sampling signal analyzer synthesizes a sampler drive signal at a sub-harmonic of the fundamental frequency of the input signal. This has the advantage over known data sampling signal measurement instruments that it is not triggered directly in response to the level of the input signal to be measured. Instead, sample timing is based on numerical analysis of the intermediate frequency (IF) signal produced by the sampler. The IF frequency can be an arbitrarily low frequency, which allows precise digitizing and digital signal processing for aligning measurement data from sweep to sweep. The sampling signal analyzer operates so that all frequency components of the input signal will lie within an IF bandwidth from a comb tooth of a sampling frequency and will translate (i.e., mix) and compress into the IF. The sampling signal analyzer determines where to mix the input signal in the IF based on the frequency of the input signal and a display time range selected by the operator. A pulse profiling method enables the recoverable modulation bandwidth of the sampling signal analyser to be as wide as a high-frequency input bandwidth so that the response of high-frequency devices stimulated by pulsed or otherwise modulated signals can be measured. <IMAGE>
